WILLIAM MEARS, OF CLEVELAND, OHIO.

STEAM WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 403,123, dated. May 14, 1889.

Application filed June 28, 1888. Serial No. 278,444. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM MEARS, of

Cleveland, in the county of Ouyahoga and.

State of Ohio, have invented new and useful Improvements in Steam-Boiler Heaters; and I hereby declare that the following is a full, true, and exact description thereof.

My-invention consists in a novel arrangement of the means for circulating the exhauststeam through a system of pipes arranged to form a heater, through which heater water passes and is heated by the said exhauststeam, there being arranged pipes in the heater for the passage of water and steam separately, as hereinafter more fully set forth in the annexed specification and shown in the accompanying drawings, in which Figure 1 is a central vertical section of the said heater, and Fig. 2 is a partial horizontal section of the same on line 50 00, Fig. 1.

Like letters of reference refer to like parts in the drawings and specification.

The outside shell, A, bottom head, B, and top head, 0, constitute the exterior form or jacket of said heater. At either end the shell A is provided with a flange, a, by means of which the heads are bolted or otherwise appropriately secured to said shell A.

The heads B and O are cup-shaped, as seen in Fig. 1, and provided with an inlet-opening, D, in the bottom head, and an outlet-opening, E, in the top head thereof. Within the interior of this structure is arranged a system of pipes which also terminates in heads F and G, as seen in Fig. 1. Each head consists of a cup and plate, I) c and b c, which parts are united by means of the screw-bolts I1 and H after the tubes I have been screwed into the plates 0 c and the pipes J placed inside the tubes and between the cups 1) b. The lower head is setupon the stands K, which project up from the bottom head, B, the entire interior arrangement being thus surrounded by space.

The water enters the heater (inside cup, respectively) through pipe L, and is forced up through the tubes I into the head G, from whence it again flows down and out through the pipe ML into the steam-boiler. To be sure that all the water does circulate through the pipes a partition, N, in the lower head, F, is provided, as seen by the dotted lines in Fig.

2. Thus all the water entering through the pipe L must rise and descend in the tubes before it can pass through the pipe M.

The steam for heating the water circulating through the tubes enters the heater through the opening D and rises as well in the pipes as in the channels 0 which are formed by the outside and inside heads. The exhaust-steam escapes through the opening E, as seen in Fig. 1, and the condensed steam or water will accumulate on the bottom of the head B.

The rim P, Fig. 1, prevents the water from flowing back into the steam-pipe which is in open relation with the opening D. The water can be drawn off by means of the cock Q. R is the pedestal upon which the heater is set.

What I claim, and desire to secure by Letters Patent, is

1. In combination, the outer jacket, a series of water-pipes within the same, the hollow heads F G at each end of said pipes, the said heads being held within the jacket and away from the walls thereof, inlet and outlet pipes for the water, a series of steam-pipes extending through the water-pipes and hollow heads, and inlet and outlet pipes for the steam, whereby the steam may circulate through and around the water-pipes and also through and around the hollow heads, substantially as described.-

2. In combination, the vertical jacket, the vertical Water-pipes within the same, the hollow heads at each end of said pipes, the steampipes, inlet and outlet pipes for the steam and.

water, and the supporting-posts K for the hollow head F, whereby all the water and steam pipes and the heads F and G are held Within the jacket to permit the steam to circulate freely.

3. In combination, the outer jacket, the series of water-pipes, the hollow heads F G, with inlet and outletpipes for the water, the steampipes and the inlet and outlet pipes for the steam, and the partition in the hollow head F, whereby the water is caused to flow through the pipes, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM MEARS.
